This guide describes how to make configuration changes in StarWind Highly Available devices. Particularly, changing an HA Partner Node, Manual Synchronization starting after failure, changing Synchronization and Heartbeat Networks, changing Synchronization priority and Challenge Handshake Authentication Protocol configuration.
Changing an HA Partner Node
To change an HA partner node, follow the next steps:
1. Right-click the required HA device and select Replication Manager from the shortcut menu.
2. In HA Device Replication manager, click the Remove replica menu button.
3. Click Yes to confirm the deletion.
4. Click the Add replica button.
5. Select the Replication Mode option.
6. Specify the Partner Node.
Click Next to continue.
7. Choose the Partner Device option.
8. Specify the device location.
Click Next to continue.
9. Click Change Network Settings.
10. Select the Synchronization and Heartbeat Channels.
11. Choose Synchronize from existing Device.
12. Click Create Replica.
13. Click Close.
If synchronization of HA device nodes does not start automatically after you bring the nodes online, start it manually or mark the device as synchronized.
1. Right-click on the device and choose Mark as Synchronized.
2. Click Yes to start the synchronization.
NOTE: If you do not know which target has to be used as a source of synchronization, check the Server Log or Event tabs of each StarWind Server. Select the StarWind service that was the last one to go offline.
3. To start the HA nodes manual synchronization, right-click the required HA device and select Synchronization from the shortcut menu.
Changing Synchronization and Heartbeat Channels
To change synchronization or heartbeat channels or replace a NIC, follow the next steps:
1. Launch StarWind Management Console and connect to the first StarWind HA partner node.
2. Right-click the required HA device and click Replication Node Interfaces on the shortcut menu.
Important note: In order to avoid the split brain issue, at least one of the Heartbeat interfaces must be active while reconfiguring Synchronization and Heartbeat channels.
3. The Network interface can be added or removed in HA Device Replication Node Interfaces manager that has appeared.
4. To add the device, click Add Interface and specify the IP address. Click checkbox to use a new interface as a Heartbeat Network. Leave this check box blanked to use the new interface as a Synchronization network.
Changing Synchronization Priority
1. To change the Synchronization priority, right-click on the needed device and choose Change Synchronization Priority.
2. Set the required traffic quotas for Synchronization Channel.
Configuring CHAP for an НA Device
1. Launch StarWind Management Console and connect the first StarWind HA partner node.
2. Right-click the HA device on the CHAP Permissions tab and click Add permission.
3. Select Authentication Type.
4. Specify the device values: CHAP name, Local secret and click OK.
Select the Mutual CHAP authentication checkbox to ensure the higher level of iSCSI security, if needed.
5. Connect to the second HA partner node.
6. Right-click the HA device and click Change Partner Authentication Settings.
NOTE: If you don’t change the partner authentication settings, StarWind will not be able to synchronize HA devices to the partner node after the service restart.
7. Specify CHAP as an authentication type and enter the Local Name and Secret specified for the first server.
Specify Local Name and Local Secret to connect to the client node.
Take the following steps on ESXi servers:
1. Launch vSphere Client and select the needed ESXi server.
2. Switch to the Configuration tab and select Storage Adapters in the Storage pane.
3. Select a storage adapter from the iSCSI Software Adapter list, go to the Properties section and choose the Edit Authentication pane.
4. Select Unidirectional CHAP.
5. Specify the CHAP Name and Secret.
NOTE: If the mutual CHAP is specified earlier, a bidirectional CHAP Name and Secret need to be specified as well.
On the Hyper-V servers, follow the next steps:
1. Launch iSCSI Initiator: Start->Administrative Tools->iSCSI Initiator.
2. Select the required Target and click Connect.
3. Enable Multi-path and click Advanced.
4. Select the Enable CHAP log on checkbox and specify Name and Target secret.
This technical paper describes possible configuration changes that can be applied to StarWind Highly Available devices. The document covers the information that can be helpful for advanced management: adding and removing HA partner node, manual synchronization options, changing Synchronization and Heartbeat networks, configuring CHAP between StarWind Virtual SAN and Hyper-V or ESXi.
